Welcome to my website!
I’m an applied environmental economist focusing on two major environmental issues, ambient air pollution and climate change.
I’m an Assistant Professor at CREST and ENSAE in Paris. I’m also a research affiliate at the IFS, Misum and the IPP.
- My current research seeks to answer three broad questions, mostly in the European context:
- What are the societal costs of air pollution? including health and non-health effects.
- To what extent do climate policies deliver health co-benefits? with an emphasis on the transport and electricity sectors.
- What are the determinants of support for green policies? with an emphasis on social norms and identity.
